The image gets stuck when NVR is playing back by single or multi-channel.
Possible Reasons:
−
Poor network between NVR and IP camera, and there exists packet loss during the
transmission.
−
The frame rate is not the real-time frame rate.
−
The NVR supports up to 16-channel synchronize playback at the resolution of 4CIF, if you
want a 16-channel synchronize playback at the resolution of 720p, the frame extracting may
occur, which leads to a slight stuck.
Step 36
Verify the network between NVR and IP camera is connected.
1)
When image is stuck, connect the RS-232 ports on PC and the rear panel of NVR with the
RS-232 cable.
2)
Open the Super Terminal, and execute the command of “
ping
192.168.0.0
–l 1472 –f
”
(the IP address may change according to the real condition), and check if there exists
packet loss.
Simultaneously press the
Ctrl
and
C
to exit the ping command.
Step 37
Verify the frame rate is real-time frame rate.
Select “Menu > Record > Parameters > Record”, and set the Frame Rate to “Full Frame”.
Step 38
Verify the hardware can afford the playback.
Reduce the channel number of playback.
Select “Menu > Record > Encoding > Record”, and set the resolution and bitrate to a lower
level.
Step 39
Reduce the number of local playback channel.
Select “Menu > Playback”, and uncheck the checkbox of unnecessary channels.
